Heh... amateurs. Seems like a pretty small-time outfit. The domain has only been registered for a little over a year, and is registered to a residential address in Omaha Nebraska. The only mention of them on Wikipedia is on the Lulz Security page...

If Google Street View is to be believed, the Black and Berg domain name is registered to this location.

Edit: On their web site, Mr. Black also lists one of his credentials as "US Citizen with the ability to obtain a Security Clearance". He doesn't say he *has* a Security Clearance, or even that he's *previously* held one; just that he can (allegedly) *get* one.

Oooh. So he's a US citizen. With no felony convictions or ties to known terrorist groups.
